How to Uninstall or Install libantlr3.2-gunit-java on Ubuntu 22.04

Updated: October 27, 2022

gUnit is a “Unit Test” framework for ANTLR grammars. It provides a simple way to write and run automated tests for ANTLR grammars in a manner similar to Java unit testing framework jUnit. The basic idea is to create a bunch of input/output pairs for rules in a grammar and gUnit will verify the expected output/result. The input can be a single line or multiple lines of strings or even an external file. The output can be simply success or failure, an abstract syntax tree (AST), a rule return value, or some text output which could be a rule’s template return value. The current version of gUnit has 2 main functions, interpreter and jUnit generator. The interpreter interprets your gUnit script and runs unit tests using Java reflection to invoke methods in your parser objects. The generator, on the other hand, translates your gUnit script to jUnit Java code that you can compile and execute by hand. I will show you how to install libantlr3.2-gunit-java on Ubuntu 22.04 in this guide.

Requirements to install

  • Operating system: Ubuntu 22.04 or older versions with more than 2GB RAM
  • Privileges: Verify that you can execute the sudo commands line.
